    1.5 ohm, 9 ohm

    Explanation:

    Total resistance, R = 10.5 ohm

    Let the resistance of one piece is r and then the resistance of another piece is 10.5 - r.

    According to question, the resistance of one piece is equal to the 6 times the resistance of another piece.

    so, 6 r = 10.5 - r

    7 r = 10.5

    r = 1.5 ohm

    Thus, the resistance of one piece is 1.5 ohm and resistance of another piece is 10.5 - 1.5 = 9 ohm.
